Not one can be lacking, or your crops may suffer nutrient deficiencies. Of course, different concentrations of different nutrients are required by plants animals at different stages of their lives. Just like young, developing children need vitamins minerals, your plants need a steady supply of calcium magnesium to ensure vigorous, healthy growth. But even expert growers often overlook another crucial element for high-value crops: specific forms of iron in precise ratios. If you're using our base nutrients, your crops are already getting the correct amounts of CA, Mg FE. But if you're using our competitors' Base nutrients, your crops could suffer from stunted growth or yellowing leaves. In that case, Use Sensi Cal-Mag extra - the nutrient supplement formulated with the ratios of CA, Mg FE your crops need. Review: Good stuff!! - I've been using this along with the Micro, Grow, Bloom series of nutrients and so far everything is going great. It's part of the PH Perfect line of nutrients AN has under their label and can be used in a variety of applications whether it be soil, foliar or hydroponics. I add this once a week and my plants are looking nice and green. I like having the option of buying smaller jugs of this stuff because I don't grow more than two to four plants at a time and I'm not having half empty bottles of calmag expire because I only use so much per cycle. I think this 1 liter will last me three cycles, maybe four but the cost between this and the competition is still significantly less when purchasing this size. I think Botanicare charges ten bucks more for a quart sized bottle with less nutrients. Review: It’s a have to - It’s calmag!!!
